Question

Table below contains estimated hours of internet usage for samples from three social class groups.

Social Class	Codes for Social Class	Hours of Internet Usage (Daily)
Upper	3	10
Upper	3	12
Upper	3	11
Upper	3	15
Middle	2	14
Middle	2	13
Middle	2	10
Middle	2	12
Lower	1	9
Lower	1	11
Lower	1	8
Lower	1	12

Each student will enter this information into a new SPSS data file. Name the first variable "CLASS" and label it "Social Class". Use the "Value Labels" of 1 = Lower Class, 2 = Middle Class, and 3 = Upper Class. Name the dependent variable "INTERNET" and label it "Hours of Daily Internet Usage".

Lastly, conduct a One-Way ANOVA test in SPSS and then answer questions #3 through #7.

Question 3

What was the mean for the middle class group? (round to the thousandths)

Question 4

What is the standard deviation for the upper class group? (round to the thousandths)

Question 5

What was the sum of squares between groups? (round to the thousandths)

Question 6

What is the value of F? (round to thousandths)

Question 7

What is the value of the associated probability? (round to the thousandths)

Answer 1
